First time on this waterway.
Tell me where the prime lays are?
Map the bottom for me and tell me why you think it lays like that.
You say you can't see the bottom so you don't know?
There are ways of getting around that.
I've added some labels to your figure.
I would start looking for fish in the large eddy below the chute. Fish will be waiting here in the slack water right along the current seam looking for food being washed down by the current. The small eddy on the other side of the chute is probably too shallow to hold many fish. There may also be some fish below the chute in the scour hole. This will be the deepest part of the pool, but if the bottom is smooth, the current may keep the fish from resting here. If there is bottom debris, then fish will be hiding behind it. There may also be fish along the undercut bank, but with the nearby fast water, it might be difficult to get a fly in there.
One last place to look is just above the chute in the pool above. During periods of low light this might be a feeding area among the rocks that form the riffle. Stealth is critical as this water is shallow.
wisconsin spring floods can be a torrent. Most holes are formed by them. Think of a race car track and the banked walls. Rocks and sediment is placed in obvious places. Any irregularity to the banking warrants some casts. That island dead center in the photos causes the floods to raise up and drop rock/sediment just on the other side of the obstruction. The full force then cuts a large bath tub sized hole there. That is the prime lay in the hole...depth....near food...
The banking on the hole above is a smaller version of the spring flood forces.
Typically opposite side of cut out is where silt lays and is shallow.
This stretch is ultra spooky due to lack of trees on most of waterway.
This a over cast stretch.
The lips all along this waterway are productive.
